ATI Teas 7 – Math Graded A

ATI Teas 7 – Math Graded A how do you find the percent increase? (ex. what is the percentage increase if original amount was 40mg and was increased to 45mg?) percent increase = new amount - original amount/original amount x 100% ex. 45mg - 40mg/40mg x 100% = 5/40 x 100% = 0.125 x 100% = 12.5% 1 kilogram = ___ pounds 1 mile = ___ km 2.2 pounds 1.609 km 1 inch = ___ cm 2.54 cm 1 gallon = ___ liters 1 quart = _____ liters 1 pound = ____ grams 1 yard = ____ feet 3.785 liters 0.95 liters 454 grams 3 feet 1 yard = ________ meters 1 mile = ____ feet 0.91 meters 5,280 feet 1 ounce =____ grams 28.35 grams 1 pound = ____ ounces 16 ounces Fahrenheit to Celsius C=5/9(F-32) Celcius to Fahrenheit F=9/5C+32 pentagon 5 sided polygon hexagon 6 sided polygon heptagon 7 sided polygon Area of any triangle formula Area of a trapezoid formula perimeter of a triangle formula A=1/2bh A=1/2h(b1+b2) P=a+b+c Perimeter of a Trapezoid Formula Area of a parallelogram formula P= a+b1+c+b2 A=bh (base x height) Perimeter of a Parallelogram Formula Area of a rectangle formula P = 2a + 2b A= length x width perimeter of a rectangle formula area of a square formula A = s² perimeter of a square formula Area of a circle formula P=2l+2w P=4s A=πr² where r=radius circumfrence of a circle formula 2πr or πd Median the middle score in a distribution; half the scores are above it and half are below it Mode the most frequently occurring score(s) in a distribution range the difference between the highest and lowest scores in a distribution standard deviation independent variable dependent variable interested (y) a computed measure of how much scores vary around the mean score variable that is manipulated (x)
